A send on an unbuffered channel can proceed if a receiver is ready.
A send on a buffered channel can proceed if there is room in the buffer.
A send on a closed channel proceeds by causing a <a href="#Run_time_panics">run-time panic</a>.

* kube-apiserver now drops unneeded path information if an older version of Windows kubectl sends it. ([#44421](https://github.com/kubernetes/kubernetes/pull/44421), [@mml](https://github.com/mml))


#### Application autoscaling

- Reduce default NodeStatusReportFrequency to 5 minutes. With this change, periodic node status updates will be send every 5m if node status doesn't change (otherwise they are still send with 10s).

- Spedup kubectl by >10 when calling out to kube-apiserver for discovery information. ([#73345](https://github.com/kubernetes/kubernetes/pull/73345), [@sttts](https://github.com/sttts))
- Fixed watch to not send the same set of events multiple times causing watcher to go back in time ([#73845](https://github.com/kubernetes/kubernetes/pull/73845), [@wojtek-t](https://github.com/wojtek-t))

* The PodSecurityPolicy annotation `kubernetes.io/psp` on pods is only set once on create. ([#55486](https://github.com/kubernetes/kubernetes/pull/55486), [@sttts](https://github.com/sttts))

- Fixed a bug that caused apiservers to send an inappropriate Content-Type request header to authorization, token authentication, imagepolicy admission, and audit webhooks when the alpha client-go feature gate "ClientsPreferCBOR" is enabled. ([#132960](https://github.com/kubernetes/kubernetes/pull/132960),...

* Adds deleting pods created by DaemonSet assigned to not existing nodes. ([#73401](https://github.com/kubernetes/kubernetes/pull/73401), [@krzysztof-jastrzebski](https://github.com/krzysztof-jastrzebski))
* Fix watch to not send the same set of events multiple times causing watcher to go back in time ([#73845](https://github.com/kubernetes/kubernetes/pull/73845), [@wojtek-t](https://github.com/wojtek-t))

* Update Cluster Autoscaler to version 1.3.7. ([#74136](https://github.com/kubernetes/kubernetes/pull/74136), [@jkaniuk](https://github.com/jkaniuk))
* Fix watch to not send the same set of events multiple times causing watcher to go back in time ([#73845](https://github.com/kubernetes/kubernetes/pull/73845), [@wojtek-t](https://github.com/wojtek-t))

- Send an error on `ResultChan` and close the `RetryWatcher` when the client is forbidden or unauthorized from watching the resource. ([#126038](https://github.com/kubernetes/kubernetes/pull/126038), [@mprahl](https://github.com/mprahl)) [SIG API Machinery]

  With WatchBookmark feature, clients are able to request watch events with BOOKMARK type. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session.
